European foreword
This document (EN 622-4:2024) has been prepared by Technical Committee CEN/TC 112 “Wood-based
panels”, the secretariat of which is held by DIN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by September 2024, and conflicting national standards shall
be withdrawn at the latest by September 2024.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
This document supersedes EN 622-4:2019.
The main changes compared to the previous edition are listed below:
a) limitation of fibre boards of type SB.LS and SB.HLS to short-term and instantaneous load duration
has been deleted;
b) denomination of those boards therefore has been changed from SB.LS to SB.L and SB.HLS to SB.HL,
respectively.
This document is one of a series of standards specifying requirements for fibreboards. The other parts of
this series are listed in Clause 2 and in the Bibliography.
Any feedback and questions on this document should be directed to the users’ national standards body.
A complete listing of these bodies can be found on the CEN website.
According to the CEN-CENELEC Internal Regulations, the national standards organisations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia,
Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland,
Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Republic of North
Macedonia, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Türkiye and the United
Kingdom.
1 Scope
This document specifies the requirements for softboards as defined in EN 316, with a density from
3 3
230 kg/ m to 400 kg/ m .
The values listed in this document relate to product properties but they are not characteristic values to
be used in design calculations.
NOTE Panels which are intended for use exclusively as thermal insulating products are covered by EN 13171.
